INTEGRATED DEVELOPMENT BOARD OF MOTOR CONTROL

Students: Mr. Hitesh Khatri Mr. Dhiraj Mahajan

• Integrated development board which can control parameters of various different motors

• The peripheral integrated circuit (PIC18F458) was used as a microprocessor to generated step pulses for the stepper motor, an angle for the RC servo motor and change duty cycle to vary the speed of the DC motor


DESIGN AND DEVLOPMENT OF TRAFFIC LIGHT CONTROLLER USING CONTROLLER AREA NETWORK

DESIGN AND DEVLOPMENT OF TRAFFIC LIGHT CONTROLLER USING CONTROLLER AREA NETWORK

Student: HARSHAL S. HEMANE

To solve the traffic congestion issue. Develop a traffic light control system

controlled by controller area network (CAN).

Traffic light controller operated by for push button

First and Second push button for operational state working in specified time

Third push button for preoperational state only yellow light is blinking

Fourth push button for stop Red light is on


Scotch Yoke Mechanism for Demonstration Purpose

The Scotch yoke is a mechanism for converting the linear motion of a

slider into rotational motion or vice-versa.

The Piston or other reciprocating part is directly coupled to a

Yoke with a slot that engages a pin on the rotating part

The shape of the motion of the piston is a pure sine wave over time

given a constant rotational speed


Development of low Cost Wind Vane for local Meteorological applications

Developed By: Miss. Apeksha Bochare

The design of a wind vane is such that the weight is evenly distributed on each side of the surface.

Digital Display of wind direction. Initial fabrication cost Appox. $50


Virtual Fab Lab Project

Developed by: Mr. Sandip Anasane & Miss. Apeksha Bochare

Almost All Fab Lab processes are in Virtual Environment available at http://coep.vlab.co.in
